1 THEORY OF FUNCTION Irrigation is one of the most important operation in agriculture. With proper irrigation the quality and quantity of crops can be significantly enhanced. Correct irrigation is not a simple process: the quantity of water must be sufficient for crops, and if not, photosynthesis and overall growth is impeded. However, if the amount of water is more than required, plant growth may become excessive producing a taller, softer and/or damaged product.
2 GENERAL DESCRIPTION The Fertigation Controller is a micro-processor-based system used in fertilization and irrigation control for greenhouses or open fields with powerful, flexible programming features. The main function of the Fertigation Controller is supplying and controlling the necessary water and fertilizers for crops according to several parameters such as acidity, conductivity and received solar radiation. The user interface is structured in two parts: 1.
3 FUNCTION DESCRIPTION In this chapter the main functions of the Fertigation Controller are presented. For a better understanding see the typical installation schemes utilized for irrigation and fertilization presented in the Installation Block Diagram, Appendix 5. 3.
- The accumulated solar radiation starting level value is used as a threshold value for the accumulated solar radiation. When the accumulated solar radiation value exceeds this threshold level the irrigation program is started (or it is brought in READY state if there are other programs currently running at that moment).
SOLAR RADIATION FACTOR: - This option can be set using panel S 42 (CORRECTIONS). This factor affects the irrigation time or volume extension in accordance with the set value of the solar radiation sensor level and solar radiation accumulation. The solar radiation accumulation extension setting and current value is displayed on panel C 06 (SOLAR RAD IRRIG). Solar radiation extension correction can be viewed using panel C 11 (SOL RAD EXTENT).
sectors using one of the following ways: - Manually - Every day at specified hour - Automatically when the accumulations counter value overflows 3.2 CONDUCTIVITY CONTROL Conductivity control is used to control the fertilization and a reading can be obtained with one to three conductivity sensors, one to two for fertilization control and one for water supply conductivity control.
3.3 FERTILIZATION CONTROL Fertigation Controller can use up to 4 fertilizer tanks. Each irrigation program can specify the percentage for each type of fertilizer. These values can be set using panel S 39 (SET FERTILIZERS). The fertilization is done in accordance with the conductivity control.
AGES). For each individual sector’s pH average see panel C 24 (SECTOR AVERAGES). All pH averages can be deleted manually or at specified time of day using panel S 61 (ERASE STATISTICS). 3.5 PID CONTROL A simplified schematic of the control (pH and EC): EC and pH control is performed using an automatic regulated system with PID controller (Proportional, Integral and Derivative). The role of this controller is to maintain a set pH and EC value within a mixing tank prior and during distribution (see diagram).
opening and closing of a valve through which a neutral solution is circulated. The amount of neutral solution added is relative to the opening of the valve, which is directly proportional to the magnitude of difference between the mixing tank pH and the set point. Control of pH implies a complex adjustment. The relation between the added reagent and the process pH is logarithmic.
can compensate for changes in the process variable (measurement) and is particularly good for slowly moving processes. When a change occurs in the process the derivative action causes the controller gain to move the “wrong” way until the measurement gets near the set point. 3.6 AGITATOR CONTROL Each of the 4 fertilizer tanks may have an agitator. An agitator can be activated in a specific tank prior to tank selection by an irrigation program.
- To erase all statistics, use panel S 61 (ERASE STATISTICS). Statistics indicates pH and conductivity averages for all irrigation programs and sectors in addition to average total irrigation accumulation. - To erase the settings of one irrigation program or to erase all settings for all irrigation programs, use panel S 62 (ERASE SETTINGS). 3.9 ALARMS The Fertigation Controller has the capability to supervise and generate an alarm for the following conditions: - Conductivity sensor out of range.
3.10 LOGGING FUNCTIONS The Fertigation Controller has the capability to log the most important occurred events and values of different parameters that can offer a description of the evolution of the entire process; The most important values are: - Number and time period of every program activation; - Filter cleaning; - Averages of pH and conductivity; - Accumulations; - Modifications to preset fertilization values (e.g.

6 CALIBRATION PROCEDURES 6.1 SENSOR CALIBRATION PROCEDURE The purpose of calibrating the Sensor’s used in conjunction with the Fertigation Controller is to compensate and adjust the output of the sensors to align with the software of the controller. As time passes the sensors change output slightly due to wear and age making calibration necessary for optimum performance. Monitoring probe performance with known standards and buffers easily identifies the need for calibration.
6.2 PID TUNING PROCEDURE For the PID controller, we have three working modes: 1. With PID regulation algorithm (Proportional, Integrative and Derivative); 2. With Proportional regulation algorithm; 3. AUTO TUNING mode. We will have one of the previous working modes as follows: K TI Td REGULATION TYPE >0 < 99.9 >0 PID >0 99.9 0 PROPORTIONAL 0 ANY VALUE ANY VALUE AUTO TUNING (DEFAULT) 1.
6.2.1 PID TUNING PROCEDURE Due to the fact that the pH and EC controls function with minimal error at the control output value, the PID controller must be tuned separately for each process (pH and EC). To access the PID parameters use panel S 57 (SET PID PARAMETERS). The displayed PID parameters are as follows: pH Factory amplification setting for pH control (controller gain). pHTi Integral constant for pH control. pHTd Derivative constant for pH control.
A. NECESSARY STEPS FOR TUNING THE PID CONTROLLER FOR PH ADJUSTMENT 1. The pH of the water source used for irrigation is measured. When this value is smaller than the reference value (is acid), the substance from the tank used for neutralization is going to be alkaline. In opposite case the neutralization substance is going to be acid. 2.
10. At the end of the program consult the log table. Write down in a table the values for the pH sensor and the time when the reading was done (see Section 4.10, LOGGING (DIARY) FUNCTIONS). 11. The obtained data is used to compose a graphic having as horizontal axis the time and vertical axis the pH variations. The next step is to analyze the obtained graphic. 12. Increment the amplification constant’s value gain (pHk) from panel S 57 (SET PID PARAMS).
- Total number of sectors = 1 - Irrigation time = 15 minute 2. Go to panel S 38 (SET SECTORS) and check the above settings. If they are different adjust them. 3. Set the reference value for EC and the range for its allowable variation (any sensor’s input value that exceeds this range will trigger an controller the alarm) in panel S 41 (COND CONTROL). 4. Make sure that all the other programs are stopped.
NOTE: The period of time for Irrigation time (15 minute default) - panel S 37 (PRE/POST IRRIG) - can be modified (increased or decreased), if the process is very slowly or very speed. Write down the final value obtained with ECk0 (for the amplification factor). For this ECk0 value, measure the oscillation period (expressed in seconds).
- The control function remains constant; however, a steady state offset is present meaning that the set point is never completely maintained. 4. INTEGRATIVE CONSTANT (pHTI OR ECTI) TOO SMALL - Integral effect is excessive. - The control variable (process) enters a state of oscillation. - A saturation effect occurs creating a “blocking effect” of the controller outputs depending on the magnitude of the error in the process. - The valve function will be unstable, opening and closing frequently. 5.
sensor #1) is outside of the allowable dead band determined by the specified pH Reference value together with the pH min and pH max offset limits. These parameters can be set using panel S 40 (pH CONTROL). 4. “EC OUT OF RANGE” This alarm is triggered when the real time value of the primary EC sensor (EC sensor #1) is outside of the allowable dead band determined by the specified EC Reference value together with the EC min and EC max offset limits. These parameters can be set using panel S 41 (EC CONTROL).
8 TROUBLE SHOOTING GUIDE THE CONTROLLER DOES NOT FUNCTION Check to insure that the proper voltage is applied to the controller. After connecting the controller to the power supply (wall outlet), the unit should initiate and the Hanna logo should appear on the LCD. If this does not occur you should check the main fuse located next to the power input connections. If changing the fuse does not solve the problem, call a Hanna Instruments Technical Support.
occurred that may not be correctable by the type and amount of acid (or base) being used. If the problem persists after checking the process pH and acid or base supply, check panel S57 (SET PID PARAMETERS) to insure that the control algorithms are correct. EC sensor out of range This indicates that the controller cannot adjust the EC value of the process within the specified range. Check panel S41 (COND CONTROL) and S39 (SET FERTILIZERS) to insure the settings are correct.
